Combining with the development of soil testing and formula fertilization in recent years, this paper studied the main ways of returning straw to wheat and straw in Jiangdu City, Jiangsu Province and their impact on the quality and yield of arable land for three years in a row. The research shows that the straw returning to soil generally can increase the content of soil organic matter, improve the quality of cultivated land, the yield and quality of crops, insist on the return of straw to perennial, not only in the fertilization stage have a significant increase in yield, and the effect is very obvious, with sustained Increase production.
